The book of Galatians in the Bible was written by the Apostle Paul. This authorship is widely accepted by biblical scholars and was uncontested in early Christian tradition. Paul wrote this letter to the churches in the Roman province of Galatia, addressing key theological issues, especially concerning justification by faith rather than by adherence to the Jewish Law. The letter is considered one of Paul's earliest epistles, likely written around 48-51 CE, shortly after his first missionary journey and possibly in connection with the events of the Jerusalem Council.
